What is the primary characteristic of a Transient Ischemic Attack (TIA)?

The primary characteristic of a Transient Ischemic Attack (TIA) is the temporary impairment of blood flow to the brain. A TIA is often referred to as a "mini-stroke" because it produces stroke-like symptoms that typically resolve within a short period, usually less than 24 hours. However, it does not result in any permanent neurological damage.

This temporary loss of blood flow can occur due to a clot or narrowing of the arteries, leading to symptoms such as sudden weakness, numbness, or difficulty speaking. Because the symptoms are transient and do not lead to lasting effects, a TIA serves as a crucial warning sign for potential future strokes. Recognizing a TIA is important for immediate assessment and prevention strategies to address underlying risks and protect the brain's health.
